Application filed January 31, 1927, Serial No. 164,941, and' in CanadaDecember 16,1926.A

'lhis invention relates to valves and particularly to a construction foruse as a pumpy provide an elevated! valve seat having a sediment chambervoutward-ly of the regular travel of the water through the valve, sothat any sediment will not be permitted to lodge' on the yval-ve seatand thus prevent a proper fitting vof the valve against the same.

A further' object is to provide an elevated valve seat having afsediment chambersurrounding the same', the bottom of the sedimentchamber being considerably lower than the valve seat. v

A further object is to provide an elevated valve seatadapted to' be usedas a pump va-live when used in pump construction, as a footvalve onthe-end of al suction pipe or as a verticalcheck valve where a pipe iscont'inued below the usual valve.

@ther objects and' advantages of my invention will become apparent.ensuing a perusal ofv the'follow-ingspecification read in conjunctionwith the annexed drawings', in which: 4 y

Fig. is-asectional viewl showing the preferred embodiment of myinvention, when usedas a foot valve on the' end of a suction pipe.

Fig. 2 is a sectional view of the preferred embodiment when used as avertical check valve between two lengths of pipe.

Fig. 3 is a modified form of a base meinber embodying the ring memberintegral therewith.

Like numerals of reference ydesignate corresponding parts throughout thedifferent views.

Referring more particularly to Fig.k 1, the numeral 3 indicates a headpreferably having a body portion of cylindrical formation. Its upper endis formed inwardly and prolvided with an open end portion 4 threaded onits inner circumference. The lower end of the head 3 is provided withthe outwardly directed flange 5. 6 indicates an `upper end annular ring,preferably having an outercircumference of the same size as the outercircumference of the flange 5. Upwardly from the inner edge of theringf6, l provide a. cylindricaly member 7. The height of thiscylindrical member 7 may be varied considerably-accordingto the use towhich the valve is to be subjected. 8 indicates a base member-preferablyhaving an outer circumference of the same size as thev annular ring 6and flange 5. Centrally of this base member 8, I provide an upwardlyextended boss 9, around which are located spaced openings 10. Ifdesired, this boss 9 may extend both upwardly and downwardly from thebase member, as shown in Fig. 3. Between the flange 5 and the annularring 6, I' provide a gasket or washer 14, which may be made of anydesired material commonly used for this purpose.

. The boss 9 is provided with a central vertical openiiig yas at 15, inwhich a stem4 16 is adapted to .be reciprocally mounted. This stem 16will act as a support and guide for properly seating a valve disc,hereinafter mentioned. The upper end of the stem 16 is provided with anenlarged head 17, which 'preferably has an annular `outer circumferenceand its upper surface convex. Positioned under the yhead 17 and tted onthe stem 16 is a valve disc 18, preferably having an outer annularcircumference parallel with the outer annular circumference of thecylindrical member 7 .v 19 is a jam nut threadedly Aengaged on the stem16 and adapted to tighten thevalvedisc 18 against the'under face of thehead 17. The lower end of the stein 16. isr threaded tol receive the nut23 near its lower extremity. A cotter pin 24 is fitted through the stem16 under the nut 23, so as to prevent the nut 23 from coming disengagedfrom the stem 16. By lhaving this nut 23 positioned on the stem 16, thestem will be retained in the boss 9 against disengagement therefrom.

It will be noted from the drawing, Fig. l, that the under face of thevalve disc 18 will normally rest on the upper flat face of thecylindrical member 7 which will act as a valve seat. If desired theupper end of the cylindrical member 7 may be iianged inwardly to providea greater seat capacity when found necessary. It may be found to be ofadvantage to have the seating face, at the of the cylindrical member 7,tapered with the outer or inner edge slightly 'base 8 and the annularflange21',-I provide registering openings through which the bolts 11 arefitted, which bolts 11 when tightened into position by the nuts 12, willretain these parts in fixed position as'shown in Fig. 1. Vhen the-valveis to be used as a foot valve, this receiving chamber 1s preferably of abowl yshape formation and provided with a number of spaced yopenings 22,through which' the wateror other fluid may enter. In having theseopenings 22 of a pre-deter mined size, this receiving chamber will act'as a strainer' and will not permit any undesirable foreign matter to besucked into the valve. y

Referring more particularly to Fig. 2 of the drawings, it will be notedthat the same construction shown in all the various element-s, with theexception that the receiving chamber 20 is of a different formation.This receivingchamber 20, in Fig. 2 of the drawings, is preferablyformed of a similar size and style'as thehead 3.

y Its lower end is adapted to have threadedly engaged therein a pipe asshown. When this type of receiving vchamber is used, a second gasket orwasher 14 is used between the flange 21 and `thering 6 so as to make awater tight fit therebetween. K p

Fig. 3 shows a modified form of base member '8 which embodies theannular `ring 6. The cylindrical member 7- being integral Awith'thebase8, which will eliminate the necessity of two fittings for certainrequireA ments where this form may be found desirable.

`Throughout the specification'fand in the drawings, it will be notedthat I refer to the body portion of the headB and the member 7 as beingcylindrical in formation. I do not wish to limit myself to having theseparts cylindrical, as .it mightbefound advantageous tovhave them square,oval or kof any desired formation, in which case, the cor-operativeparts would be shaped to work in connection thereto. l

The foregoing specification and annexed drawings discloses thepreferredembodiment of my invention,.but it is to be ,understood that minorchanges may be resorted to in the commercial adaptation of myinventionwithout departing from the scope ofthe invention as hereinafter claimed.

l/Vhat'I claim as new is v 1. In a valve comprising a kcylindricalmember having an annular flange protrud-` ing outwardly from itsinner-.,end; `a valve adapted to be normally seated/on theouter end ofsaid cylindrical member; a boss, supported.` internally of saidcylindrical .mem-

ber, through which the stem of said valve reciprocates and the flange ofsaid cylindrical member being fixedly secured between the receivingchamber andthe head portion of apump construction.

2*. In a valve comprising a cylindrical :1-

member having an annular flange protruding outwardly from its inner end;arvalve adapted to be normally seated on the outer end of saidcylindrical member; a boss, supported internally of said cylindricalmem-v` ber but independent thereof, throughl which the stem of saidvalvereciprocates and the flange of said cylindrical member beingfixedlysecured between the receivingv chamber and the head portion of apump construction.
